Brewing a Double Chinook IPA

After brewing a Chinook Session IPA a few months back I started looking around for a double Chinook recipe. While I was looking for an Arrogant Bastard clone I started reading this thread over on Home Brew Talk. It featured all Chinook hop additions. With a little modification I was able to up the grain percentage to create a double IPA.

This turned out to be a great IPA. It did take longer to carbonate in the keg than I would have expected. It was fully carbed in about 3 weeks. Though it was very drinkable at 2 weeks.
